Answer:
this is 8 p
Step-by-step explanation:
A. d=45t
b. 112.5 miles. 112.5=45•2.5
It's 14.285714%
So, simplified it would be 14.3% because you round the 2 up since theres an 8 behind it.
Answer:
θ = -33.69°
Step-by-step explanation:
For Φ>0 and Φ<0 (in general Φ≠nπ where n is an integer), sin(Φ) ≠ 0
Dividing both equations:

Therefore:
arctan(θ) = -2/3
θ = -33.69°
The answer does not depend on the sign of Φ, in fact we just need that the sine does not become zero, which occurs when Φ is equal to an integer times π (radians) or 180 (degrees)
Have a nice day!
